Cheers Steve - tried the usual suspects but they cant track them down for some reason. Keen to save on the cost as I have already managed to have a bit of the Fiat I have hired 'drop off' on the motorway ! More money to fix that now as well .

So to close this out - lots of umm and ahh on the phone to all concerned , but the main dealer can now get the bits tomorrow and fit them & is trying to get it done under warranty . They even offered this without me prompting them. If not its a £300 bill .
